This adds some sync.sh improvements to make it handle errors more
gracefully.
It also updates asnes a good bit. All of the four base processors now
have all publicly accessible functions right at the top of the main
headers, and everything else is private. This is to allow these headers
to essentially take the place of the previous base classes in the old
bsnes-merged format. So if there's something public there, you need to
implement that exact function to make your own module.
I removed the frame counter from the PPU, as it has nothing to do with
emulation. That now resides inside the Qt -> SNES interface code. Quite
amazing, I was actually saving the frame counter into the save state
files before, yuck.
Removed some baggage in the System class: it was friending a bunch of
long-dead functions and classes.
Forgot to re-add the CHEAT_SYSTEM define to info.hpp, so that's been put
back.

This fixes libsnes and debugger builds, and collapses bsnes/ppu/bppu to
bsnes/ppu and bsnes/dsp/sdsp to bsnes/dsp. It also introduces
bsnes/sync.sh, which will synchronize all of asnes/ with bsnes/,
excepting the custom speed-focused modules. So far, that's bsnes/ppu
(scanline renderer) and bsnes/dsp (state machine.)
Should make keeping the two ports in sync much, much easier. It's
basically the same thing as before, only you run sync.sh and have a few
duplicated folders now. May make it clearer by creating a stub/ or src/
folder inside bsnes to do all of the copying, so that you only see the
custom folders in bsnes/' root directory.

This release greatly polishes the user interface, adds a new cheat code search utility, adds the snesfilter library, and adds Qt-based GUI support to both snesfilter and snesreader. snesfilter gains 2xSaI, Super 2xSaI and Super Eagle support, plus full configuration for both the NTSC and scanline filters; and snesreader gains support support for multi-file ROM archives (eg GoodMerge sets.)
Statically linking Qt to bsnes, snesfilter and snesreader would be too prohibitive size-wise (~10MB or so.) I have to link dynamically so that all three can share the same Qt runtime, which gets all of bsnes and its modules to ~1MB (including the debugger build); and Qt itself to about ~2.5MB.
However, there is some bad news. There's a serious bug in MinGW 4.4+, where it is not generating profile-guided input files (*.gcno files.) There is also a serious bug in Qt 4.5.2/Windows when using dynamic linking: the library is hanging indefinitely, forcing me to manually terminate the process upon exit. This prevents the creation of profile-guided output files (*.gcda files.) It would be tough enough to work around one, but facing both of these issues at once is too much.
I'm afraid I have no choice but to disable profile-guided optimizations until these issues can be addressed. I did not know about these bugs until trying to build the official v053 release, so it's too late to revert to an all-in-one binary now. And I'm simply not willing to stop releasing new builds because of bugs in third-party software. As soon as I can work around this, I'll post a new optimized binary. In the mean time, despite the fact that this release is actually more optimized, please understand that the Windows binary will run approximately ~10% slower than previous releases. I recommend keeping v052 for now if you need the performance. Linux and OS X users are unaffected.
Changelog:
- save RAM is initialized to 0xff again to work around Ken Griffey Jr Baseball issue
- libco adds assembly-optimized targets for Win64 and PPC-ELF [the latter courtesy of Kernigh]
- libco/x86 and libco/amd64 use pre-assembled blocks now, obviates need for custom compilation flags
- added a new cheat code search utility to the tools menu
- separated filters from main bsnes binary to libsnesfilter / snesfilter.dll
- added 2xSaI, Super 2xSaI and Super Eagle filters [kode54]

- added folder creation button to custom file load dialog
- fixed a few oddities with loading of "game folders" (see older news for an explanation on what this is)
- updated to blargg's file_extractor v1.0.0
- added full support for multi-file archives (eg GoodMerge sets)
- split multi-cart loading again (BS-X, Sufami Turbo, etc) as required for multi-file support
- cleaned up handling of file placement detection for save files (.srm, .cht, etc)
- file load dialog now remembers your previous folder path across runs even without a custom games folder assigned
- windows now save their exact positioning and size across runs, they no longer forcibly center

- debugger's hex editor now has a working scrollbar widget
- added resize splitter to settings and tools windows
- worked around Qt style sheet bug where subclassed widgets were not properly applying style properties
A new version of bsnes has been released. It contains a few minor emulation fixes, as well as user interface improvements. Behind the scenes, the source has been cleaned up more in preparation for running the CPU and PPU (video processor) separately from each other (eg with no enslavement.) This is required for implementing a clock cycle based PPU renderer.
- Greatly improved invalid DMA transfer behavior, should be nearly perfect now
- Major code cleanup -- most importantly, almost all PPU timing-related settings moved back to PPU, from CPU
- Added option to auto-detect file type by inspecting file headers rather than file extensions
- Rewrote video filter system to move it out of the emulation core -- HQ2x and Scale2x will work even in hires and interlace modes now, 50% scanline filter added
- Re-added bsnes window icon
- Added new controller graphic when assigning joypad keys [FitzRoy]
- Redundant "Advanced" panel settings which can be configured via the GUI are no longer displayed
- Improved speed regulation settings
- XP and Vista themes will now apply to bsnes controls
- Added "Path Settings" window to allow easy selection of default file directories
- Tab key now mostly works throughout most of the GUI (needs improvement)
- Main window will no longer disappear when setting a video multipler which results in a window size larger than the current desktop resolution
- Added two new advanced options: one to control GUI window opacity, and one to adjust the statusbar text
Changelog:
- OpenGL (with hardware filter mode support) and SDL video drivers added to Linux port
- OpenAL (with speed regulation disable support) and OSS audio drivers added to Linux port [Nach]
- SDL input driver (with joypad support) added to Linux port
- Emulator pause option added
- Added option to select behavior of bsnes when idle: allow input, ignore input or pause emulator
- Added support to remap common GUI actions to key/joypad presses on the "Input Configuration" screen
- bsnes will now clamp the video output size when it is larger than the screen resolution
- GUI library has been enhanced, and renamed to hiro
- Fullscreen mode now always centers video, rather than approximates
- Fullscreen mode now works correctly on Linux/Openbox
- Extra layer of abstraction in src/ui has been removed, as GUI lib unifies all ports anyway
- Video, audio and input drivers unified into standard library, named ruby
- All custom headers have been merged into a new template library, named nall
- Makefile rewritten, vastly improved. Allows quick toggling of compiled-in drivers
- Makefile: all object files now placed in /src/obj, binary placed in /
- libco greatly enhanced, no longer requires an assembler to build [byuu, blargg, Nach]
- libco SJLJ driver added; bsnes should now build on any Unix-derivative now (Solaris, OS X, PS3, etc) [Nach]
- Fixed register $213e.d4 PPU1 open bus behavior [zones]
- Windows port will not activate screensaver while bsnes is running [Nightcrawler]
- Visual C++ target no longer requires stdint.h
- And lots more -- mostly code refactoring related
This version replaces libui with miu -- a new GUI wrapper library, and cleans up large portions of the source code.
Unfortunately, the GUI rewrite took far, far longer than I ever imagined. As a result, no work has gone into the core emulation for this version. But with the GUI rewrite out of the way, that should change in the near future. And thanks to the new UI library, I can now begin work on adding a cross-platform debugger to bsnes, at long last.
Changelog:
- Major source code cleanup (lib/, ui/miu/, ui/vai/)
- Cheat code editor was broken in v0.026, this is now fixed
- Cheat code file format simplified for human readability
- Makefile install target improvements [belegdol]
- libui replaced with miu GUI library
- Custom video / audio / input drivers replaced with vai HW library
- ppc and ppc64 libco targets added [Vas Crabb]
- x86 and x86-64 libco targets now work on OS X [Lucas Newman]
